HERMAN WINTER, OF BOSTON, MASSACHUSETTS, ASSIGNOR T() JAMES GREGORY, OF NEW YORK, N. Y.

IMPROVED FASTENING FOR DECYK AND SIDE LIGHTS 0F VESSELS.

Specification forming part of Letters Patent No. 42,058, dated March 22, 1864.

To all whom it may concern:

Beit known that I, HERMAN WINTER, of Boston, in the county of Suffolk and State of Massachusetts, have invented and made a `certain new and useful Improvement in I-ast` enings for Deck and Side Lights for Vessels; and I do hereby declare the following to be a full, clear, and exact description of the said invention, reference being had to the annexed drawing, making part of this specification, wherein I have shown a sect-ion of my said fastening as applied to a side light.

Deck and side lights for vessels have heretofore been made as a metal frame. secured t0 a metallic ring that is permanently attached to the vessel, and screws and turning buttons have been employed to compress the frame carrying the glass against the fixed ring, so as t0 render the light water-tight. The screws employed for such purposes are provided with handles by which they are turned, and have also been formed with a neck on the shank of the screw, into which the end of a small screw passes, in order that the screw may be retained in the frame of the light, but be capable of being entirely unscrewed before the light is removed from its seat, as may be seen in Letters Patent granted to John Sutton and James Gregory, April 28, 1863.

Thenature of my said invention consists in a collar attached around the shank of the fasteningscrew, passing into a recess in the frame carrying the light or glass, whereby the screw is prevented from falling out when unscrewed. The screw is not weakened by having a neck formed on the shank, and the screw can be entirely unscrewcd before the light is opened; or the light can be shut tight-ly to its place and held by hand until the fasteningscrews are turned into their places.

In the drawing, a represents the ring or frame that is to be attached permanently to the vessel, either the deck or the side. bis the metallic frame carrying the glass e, as usual, and this frame b may be connected to a by hinges. d d are the handles of the screws e e, which screws pass into the ring a to hold p the light tightly to its elastic bed j'. g g are The collar g, applied to the shank of the fastening-screw of a deck or side light, in combination with the recess It in the frame carrying the glass, for the purposes and as specied.

In witness whereof I have hereunto set my signature this 16th day of January, 1864.

HERMAN WINTER.
